Moreover, with rapid advances computing technology, complexity computational overhead that can be feasibly incorporated any developed technique dramatically improved. Thus, would impractical for implementation just a few years ago now realistically applied....

Automotive manufacturers are continuously striving to meet economic demands by designing and manufacturing more efficient better performing vehicles. To aid this effort, many using different design strategies such reduce the overall size/weight of certain automotive components without compromising strength or durability. Stainless steel is a popular material for uses (i.e., bumpers fuel tanks), since it possesses both high ductility, relatively light its strength. However, with current...
